Repotting Christmas cactus
Our Christmas cactus has roots growing up out of the soil. Before we re-pot we would like to know how long do the roots get and is it okay to pot the cactus in a pot big enough to accommodate the plant for its life or should we pot to it’s current size and keep re-potting as it grows?
Christmas cactus do not have a large root system and they prefer to be slightly potbound. It’s better to replant in a pot that is 1 inch larger than the current pot and keep re-potting as it grows. Using too large of a container can lead to waterlogged soil which will happen when there are not enough roots to absorb the soil moisture fast enough. As a result, the roots will stay wet longer, receive less oxygen and rot.
